people remember, this is his / her mum... I'd go with this (oh maybe play some uplifting music in the background during the pitch, a powerpoint slide show might help too):
Emedded software development is a sound career choice.
In these modern times, more and more devices are produced with high levels of automation and all of these require a some sort of code running on atleast a microcontroller, or a cpu.

Embedded software developers are in short supply.

The ARM series of CPUs are well regarding in the electronic / software engineering community as a stable and viable platform for modern systems design.

Learning to write code for the GP32 is an excellent way to get started in the business, and hoan the skills required to build highly optimized executables for a generic embedded design paradigm.
<flick to a flow chart entitled 'Real time OS development flow' or somesuch buzzword>
Armed with these skills, you will surely grow up to become an assest to civilisation as you help produce the next wave of technological advances, improving the daily lives of your fellow mankind.

Yes that's right the GP32 is the vision of the future, securing your place amonst the few who have given us such fantastic advances as,
the printing press,

the light bulb,

the electric hair dryer
<someone from the 60s with big hair>
and tetris.

<switch off the music or change the track to some depressing classical number invovling a chello>
Without the gp32, you will grow meek and lame, bored and souless, quite possibily turning to drugs, gambling, and easy women (or men). You will then no doubt become a criminial to help feed your roller coaster style habbit, which will inturn probably result in you commiting murder and spending the rest of your life in prision.

Hope this helps, let us all know how you go.
